HYDROCARBON-BU RN ER.

SPECIFICATION forming part of Letters Patent No. 605,554, dated June 14, 1898. Application filed June 22, 1896. Serial No. 596,408, (No model.)

To all whom it may concern;

Be it known that we, JAMES M. MERRITT and BENJAMIN F. GooDRIoII,icitizens of the United States, residing at I-Iomer, county of Calhoun, Stateof Michigan, have invented a certain new and useful Improvement in Hydrocarbon-Burners; and we declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to v make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Our invention has reference to an improved hydrocarbon-burner, the same being more particularly designed for use in oil-stoves; and it consists of the construction, combination, and arrangement of devices and appliances hereinafter specified and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a side elevation illustrating features of our improved burner.- -Fig. 2 is a vertical cross-section therethrough on the line 2 2, Fig. 1.

The object of our invention is to providea burner of this description of superior simplicity and utility, and we carry out our in- I vention as follows:

A indicates a wick-tubeof the Argand type formed with tubes at a,,forming an annular chamber, in which is located the Wick A, said wick-chamber forming an interior air opening or chamber A B B denote inner and outer foraminous 7 Walls forming an intermediate combustionchamber 1) above the wick-chamber and an 7 interior air-chamber B communicable with the chamber A within the wick-chamber. To regulate the circulation of air through the opening or chamber A and the chamber B into the combustion-chamber through the able distance from the inner wall B, and the diaphragm D,'located intermediate the cylinder 0 and wall B, closes the space therebetween,-so that air cannot'pas'supward enterior to the cylinder 0, intermediate said cylvert the circulation of air and compel it to passthereabout upward between the fora'minous cylinder and the inner wall of the wickchamber, s'aid'cylinder being spaced also from the inner wall of the wick-chamber to allow the air to pass outward therebetween. The circulation of air will thus be directed into the chamber 0 of the cylinder. The closed head C of said cylinder will compel the air to pass out of the cylinder through the sides of the cylinder above the diaphragm D into the chamber B from whence the air may pass through the inner foraminous Wall E into the combustion-chamber b as the draft through the said combustion-chamber may: require. Above the chamber B is located a cap E, projecting downward below the upper portion of thecombustion-chamber, a diaphragm F being located below the base of the cap'E, sepmating the interior chamber E of said cap from the chamber B said diaphragm being provided with an opening f, through which the'adjacent chambers may communicate the one with the other/ The cap E is provided with an orifice e at the top thereof.

The diaphragms D and F may be supported in any" suitable manner, as by forming the wall B with supportingbeads, upon which said diaphragms may rest, respectively.

' The diaphragm D is also engaged with the cylinder 0' in any suitable manner, as by means of rivets or bolts d.

' Gdenotes a drum or cylinder located above the outer foraminous wall B and spaced therefrom, forming an intermediate air-chamber G. At the base of said chamber G is located an annular foraminous plate H, through which air is admitted into the chamber G, from which chamberthe air may be drawn into the combustion-chamber I) through the foraminous wall 13. The plate Il may be sup ported in any suitable manner, as by brackets ll. Said plate II is preferably provided with an outer flange 71, within which seats the lower end of the cylinder G.

J denotes a top plate located above the chamber G and extending over the top of the combustion-chamber I).

K denotes any suitable wick-raisin g device.

The base plate ll is provided with upwardly-projecting cam-flanges 11 the cylinder G being provided with lugs g to ride on the upper edges of said cam-flanges to lift the cylinder G when it is desired to light the burner. The cylinder G is indicated in lifted position in dotted lines, Fig. 1.

The top plate J is made open, with crossarms J, said plate resting upon the drum G, the foraminous wall 13, and the cap E.

By means of the cylinder 0 we are enabled to control and modify the supply and circulation of air through the chamber A and upward therefrom and deliver to the combustion-chamber a steady and regulated flow of air. If it were not for the cylinder 0, the air would be supplied to the combustion-chamber in too large quantities, which would result in producing an illuminating-ilameinstead of a blue flame. By introducing the cylinder 0, having a closed base or head 0 the stronger currents of air are obstructed and retarded and introduced through the perforated wall of said cylinder. Thereby the air is delivered to the combustion-chamber in just the required amount and carried to a point above the plate D and introduced through the wall 13 at a point sufiiciently above the top of the wick-chamber to secure better combustion.

The plate J is merely a skeleton frame to hold the different parts adjacent thereto together.

The cap E closes the upper end of the inner chamber formed by the wall B, with the exception of the central orifice in said cap, the upward circulation of the air through the cap being controlled by the size of said orifice.

The cylinder G is a solid outside shell inclosing the upper part of the combustionchamber of the burner.

It will be seen that the top plate J, with its arms J, connects the casing or cylinder G with the foraminous walls forming the combustion-chamber. The base-plate II is preferably provided with an inwardly turned flange 71., abolt g uniting said latter llange with the top plate J and holding the adjacent parts together.

\Vhat we claim as our invention is 1. In a burner, the combination of a wickchamber of the Argand type, forming an in terior air-chamber, foraminous walls located above the wick-chamber forming a combustion-chamber therebetween, an interior airchamber formed by and within the inner wall, a foraminous cylinder at the adjacent ends of said air-chambers, said two air-chambers communicable the one with the other through said cylinder, substantially as set forth.

2. In a burner, the combination of awickchamber of the Argaud type, forming an interior air-chamber, foraminous walls located above the wick-chamber, forming a combustion-chamber therebetween, an interior airchamber formed by and within the inner wall, a foraminous cylinder provided with solid heads at the top and bottom thereof, located at the adjacent portions of said two air-chambers, said cylinder spaced from the interior walls of the wick-chamber and the combustion-chamber, and a diaphragm located exterior to said cylinder to divert the circulation of air through said cylinder,said air-chambers communicable the one with the other through said foraminous cylinder, substantially as set forth.

In a burner, the combination of a wickchamber of the Argand type, forming an interior air-chamber, foraminous walls located thereabove, forming a combustion-chainber therebetween, an interior air-chamber formed by and within the inner wall, a foraminous cylinder located at the adjacent ends of said air-chambers, through which said air-chambers communicate,the one with the other, and a cap located above the air-chamber within the combustion-chaml)er, said cap provided with an opening to permit the circulation of air therethrough, substantially as set forth.

'-l-. In a burner, the combination with foraminous walls or tubes 1 3, of a cylinder or casing G thereabout, forming an air-chamber therebetween, a top plate J connecting said cylinder or casing to said foraminous walls, and a perforated plate H at the base of said air-chamber, said plate formed with camflanges H and said casing or cylinder G provided with lugs g to ride on the upper edge of said flanges to lift the cylinder or casing, substantially as set forth.

In testimony whereof we sign this specification in the presence of two witnesses.
